'llnz planlt 15 as constructside flanges 1G. 1G toserveas guides for, and to constitute :1 pocket for a bolster 17. -At the extreme'ends of the plank 15 are} formed side flanges 18, 18 and a bottonj the side flanges 18 and the bottom flange -19} extends through pocket-s formed in the side; frames'S; Shy vertical flanges 20, 20, and-a horizontal bed QL' "It willbe understood'that all of the structural members herein described are suitably -webbed in form to provide the maximum; strength with the *minin'nn'n weight.- The. bed 21 is provided vwith a recess formed therein, having an elongated curved bottom longitudinally disposed ineach of the frames 8; The recesses are'transrersely shaped to a short curve, all square surfaces or corners ilrthese recesses being'avoided, as thesame form arm-king pocket for a rocker 22 which is extended from the bottonrflange 19 of the spring plank 1f).

The flanges-1S, 18 are vertically elongated to fit within the pocket formed by the flanges 20, 20 in the frames 8. The said flanges 18 are curved at their upper edges to permit the extension of thesaid flanges in the said pocket after the rocker 22 is seated in the lre'eess" provided therefor. The inner edges of the flanges '18, when the sameare extended'withiii the pocket formedby the flanges 20, are disposed sniliciently close-to the top of the frames 8; to prevent the lift-of the plank 15 to'rai Se' the rocker 22 out of the recessprovidml in; the bed 21.

this without bolts bein" used, 'to ,secure the i fi Peek, 1.- h -l js" em -H 1* w ed by me is formed withverticallyextended i flange 19. The box-like structure formed by;

of thetrl1ele,..together with the journal boxes 10, are' then connected to the frames 8, 8, andjthe frame of the truck is complete, and

' nally, the weight applied to the spring plankupon the springs 24,

also be noted that the connection thus formed between the side frames 8, S by means of the spring plank l5 and the rockers 22, 22 thereof, is such that'a certain amount of independent action on thepart of-the frames 8, 8 is by this construction will also be noted by reason of the conn 0- tion between the rocker-s22 and the recesses formed in the bed 21, that while, the frames 8, 8 may be rocked laterally and longitudi- 15 will force the rockers 22 to seat within the recesses in the bed 21, and thereby right the parts, or cause the sameto resume the normal position when moved therefrom.

The spring plank 15' is provided at each end with a platform 23, 23. The platforms 23, 23 are provided to receive buffer springs 24, 24. The springs 24, 24- are mounted in the usual manner, and are provided to support the bolster 17. The bolster 17 is seated 24 and guided between the flanges 16, 1,6, the said bolster being provided with end extensions 25, 25 to thus operate as a guide. The bolster 17 is provided with a central bearing ring 26 and -a bolt j hole 27 for the king bolt, whereby the'same to the connections thereof, and

understood that the S1 is secured upon the locomotive tender or car for which the said truckis provided.

The truck thu's constructed is particularly designed for-locomotives and tenders. It will be seen that when attached to rapid running cars'the forward wheels, in striking a curve in the track, receive a severe impact on the flange of thewheel. when the truck is rigid, is exceedingly trying is a strain upon the car structure to which it is attached. By providing a yielding truck structure adapted to give-to the impact and strain, as is the truck her'oindcscribed, the shock of the impact is dissipated,-'and the car and truck structure are relieved from the rending action of the impact. Further it will be ight fore-ant aft movement permitted by the rocker 22 provides for an adjustment of the truck longitudinally to a change of grade, or permits the truck to rock slightly f0IWfll(l"('\'ll0Il the brakes a're'applied, and the checking strain to overcome the inertia of the enginels upon the-wheels of the truck. Also, the transverse curvature of the rockers 522 permits a slight transverse rock of the fr'gunes 8, 8 and the bolster 17 to relieve the torsional strain due to the overcoming" of the inertia of the en-.

gine body when entering upon a'curved sec- Lion of track.
